OK i screwed up, and though much googling i have not found the answer i was looking for. A customer of mine wanted a server built. OK no prob. Built the server setup the raid (2 x 1Tb Hitachi's Newegg.com - HITACHI Deskstar 7K1000 HDS721010KLA330 (0A34193) 1TB 7200 RPM 32MB Cache SATA 3.0Gb/s Hard Drive - OEM ) On a Tyan S2912WG2NR-E Newegg.com - TYAN S2912WG2NR-E Dual 1207 NVIDIA nForce Professional 3600 Extended ATX Server Motherboard - Retail I am running Server 2003 R2. well it all runnning fine except one problem I screwed up and setup the RAID in RAID 0 instead of RAID 1. I cannot have this macine down for more than a hour. so a full reinstall is not an option, as i have several hours on setup. There is about 400gb of data on the drives. It is a file server along with a exchange server. Does anyone have any ideas here??

I have access to one more 1tb drive that i can move data too if needed.

Thanks in advance!

Not gonna be able to do it sorry. Unless you did 4 drives for raid 0 and then a raid 1 of that raid 0

If you absolutely can't have the downtime then you will probably need to build another server. Even if it would work all the raid migrations I have ever played with took much more than 1 hour, especially with that much data on the system.

I suppose you could restore the system to different piece of hardware that has enough storage space. Fix the Raid array, and then do another backup/restore to the original piece of hardware. I have done something similar using UltraBac 8.2 when we have installed larger drives onto one of our data servers.
Issues like this are why I always recommend 5 drive setups. 2 mirrored for the OS and the other 3 in Raid 5 for redundancy.

Assuming you have Ghost, backup the RAID 0 to an image file.
Put said image file on drive A.

Option #1 (requires RAID chipset in Machine B to be the same as in the server)
Create RAID 1 array on Machine B
Take drive A out of Server and put into Machine B
Boot into Ghost Recovery Disk (loading RAID drivers via F6)
- also hoping Machine B is not using RAID via nForce4 chipset for other reasons
Restore image from drive A onto RAID 1 array.
Take server down, load RAID 1 array into server, boot away.

Option #2
Take drive A out of Server and put into Machine B
Boot into Ghost Recovery Disk
Restore image from drive A onto drive B.
Take server down, set BIOS to boot from drive B, boot up
Once in windows, erase Ghost image from drive A
Goto Admin Tools-Computer Management-Disc Management make RAID 1 array from current drive and the drive formerly housing the ghost image.

ah ha!! thanks! IDEA!! I am going to install the other harddrive into the machine. using windows own partitioning, i am going use the drives in RAID 0 and the other drive in a kinda hybrid RAID 1. using the RAID 0 as one drive inthe mirror. then using the new drive as the other one. then after it gets done rebuilding, i am going to pull down the RAID 0. then using one drive from that rebuild the RAID1. think that will work??

You need identical file space to make a RAID 1 partition.

My thoughts,

Make a image of the drive, network it onto another drive (1TB you would need of course)

With the new image of the server on one disk, cut the power(at least shut it down), swap the drive with one of the RAID 0 drives, and then boot into the drive controller, and build the RAID 1 array, as fast as possible. Bam you will boot up to a newly mirrored 1TB set.

Now this assumes you have access to another 1TB drive, knowing you though, you probally do.

Also assuming you can have it down for the complete Mirroring time, with 1TB and about 400GB used, might take about 4-6 hours, even for scsi drives.

Good luck there...

no you don't. it will default to the smallest drive in the raid, in this case 1tb. in a GM Access server at a dealership i was doing some work for, STG (the parent company that farms out IT) sent me a 80gb and a 40gb for Raid 1 drive replacements. worked fine. but the 80 only formatted to the size that the 40 was (something like 38.9gb or something). but i am going to try. If not, then i am going to add another 2 1tb drives and make a RAID 0+1....

I was mentioning for the fact of the 2TB array you have, you would need another 2TB to cover it, being that you only have 400GB, 1TB drive should work fine.
